an exception is raised on query execution:
org.datanucleus.exceptions.NucleusException: The key value passed to construct a SingleFieldIdentity of type "class javax.jdo.identity.StringIdentity" for class "class dbobject.Application" is null.

NUCMONGODB-45 fixed all of that and other things. Obviously you could contribute tests to the test suite if you think you have some other situation.
PS For future reference, all bug reports have to be accompanied by a valid testcase
